我正在使用a帧，我想对视频应用着色器以修改视频的显示。.我不知道从哪里开始。.
<!DOCTYPE html>

<meta name="apple-mobile-web-app-capable" content="yes">
<script src="https://aframe.io/releases/0.2.0/aframe.js"></script>
</head>
<body>
<a-scene>
<a-assets>
<video id="video" autoplay loop="true" src="video/Video.mp4" webkit-playsinline>
</a-assets>
<!-- Using the asset management system. -->
<a-video src="#video" width="16" height="9" position="0 1 -1"></a-video>
<!-- Defining the URL inline. Not recommended but more comfortable for web developers. -->
<!--<a-video src="video/Video.mp4" width="16" height="9" position="0 1 -1"></a-video>-->
</a-scene>
</body>
</html>
有什么主意吗？
